No, it's just carbon and GFO and I don't like using GFO, too aggressive for me and I always had stability problems trying to predict when it was depleted. Your plan sounds good.

Mark your tank has come a long way. I'm very impressed. Keep it up buddy. You have me very curious about phosphate RX. I'm still using ROWA out of habit (and it works), but I would love to move away from it one day.

Thanks Rich, that means a lot.
I wish I was more sure about Lanthanum buildup in the system. Every day I have a little more and so far there have been no issues, but everything is always fine until it isn't.
Could it be why some acros refuse to color up, or is it something else. The biggest thing for me is that I have living acros rather than dead ones. A big first step.

Still going strong, growth and colors are much improved. I lost my favorite pink acro for unknown reasons. In the past I might have reacted but I let it die without doing any significant changes. It didn't like something, not sure what.

I am but it may interfere with the health of some SPS if LC makes it into the display. I upped my dosing to 4 drops daily just before losing the pink acro and it may have played a part in it's demise. I have since reduced to a single drop in the first sump chamber and everything has stayed stable or improved. It's really hard to say if that did it, or if it was something else. PO4 is around .05 now.
Everything looks good Mark! Question, if you have a brown sps, do you try moving it up into higher light? if so, about how long does it take to go from brown to colored? would the opposite be true for paler frags?
OP

Thanks.
I have a couple of brown frags I've yet to color back up after a year of brown. Growing and healthy but brown. Pale indicates not enough nutrients, rich brown but healthy indicates something else. Sometimes acros just wake up, sometimes they don't.
Take this one, for example. it woke up and started to grow but the left side is still dirt brown and will not color up. Go figure.
In my limited experience healthy acros that are going to color up will do so even in lower PAR. Some times acros just don't adapt to tank like, especially mariciltured and/or wild caught, and will refuse to color up or just up and die after a while.

Thanks!

Messing around with a new D5500 (edit: wrote the wrong number) camera body. Higher ISO has a lot less gain, allowing me to close the aperture and get more depth of field. This angled shot at a milli I placed lower down in the tank came out quite good, ans also shows just how invasive the Xenia is. Because it's harmless to pull and remove I let it grow, then prune every few weeks. SPS seem to enjoy any Xenia 'smoke' that results from pruning.
